Robin Summeretto and Aventurine Waveflair — Summer Alts Confirmed
As previewed earlier this week, two of the game’s most popular characters are getting summer alternate forms in Version 4.5, and the stream confirmed their kits, paths and phase slots.
Robin • Summeretto (Phase 1) is a five-star Wind unit on the Remembrance path. That’s a meaningful change from the original Robin’s Harmony/Physical kit — she plays differently, not just looks different. She headlines Phase 1, which opens on 26 August alongside a Hyacine rerun.
Aventurine • Waveflair (Phase 2) is a five-star Quantum unit on the Elation path — a genuine playstyle departure from the original’s Preservation/Imaginary build. He arrives in Phase 2 alongside an Ashveil rerun.
What Else Is in Version 4.5
Version 4.5 goes live on 26 August 2026, with maintenance beginning the afternoon of 25 August. The patch runs for five weeks. Here’s what to expect:
- New location — Astropolis: an IPC-operated resort destination where the Astral Express crew heads next, picking up directly from the Version 4.4 story conclusion. Think upscale beach resort, but in space.
- Events: a racing event set in Astropolis is confirmed, with additional activities spanning the five-week period.
- 10 free Special Star Rail Passes: log in for seven consecutive days after launch and they land in your in-game mailbox — useful regardless of which banner you’re targeting.
Should Singapore Trailblazers Pull?
Both alts are mechanically distinct enough that owning the original does not make the summer version redundant — Robin Summeretto’s Wind Remembrance kit opens team compositions that the original Harmony Robin cannot slot into, while Aventurine Waveflair’s Elation path gives him a completely different role in combat. Neither is a straight upgrade; they’re lateral expansions of your roster.
For Singapore players deciding between the two phases, the practical question is whether you need a Wind Remembrance unit before you need a Quantum Elation unit in your current teams. The 300 free Jades from tonight’s codes, combined with the 10 free passes at launch, give you a small head-start either way. Check the Game News section closer to 26 August for a full banner and build rundown once more kit details are confirmed.
